When building the bms_monitor project, you may see the following warning:
Warning[Lt009]: Inconsistent wchar_t size assert.obj(libbms_stack.a) and 239 other objects in 4 different libraries have wchar_t size 16 bits bms_monitor_api.o and 26 other objects, some of them in dl7M_tln.a and 8 other libraries have wchar_t size 32 bits
This occurs because the stack library for WBMS was built using IAR 7.x, and the wchar_t size changed in IAR 8.x. The stack and bms_monitor application do not use wchar_t so it is safe to ignore this warning.
You can suppress it in the project settings:
In Project->Options->Linker->Diagnostics
Select Suppress these diagnostics and specify Lt009
